The outer race ring (25) and the inner race ring (26) of the bearing are axially secured in the housing (11) and on the shaft (12) resp. In order to make possible a limited axial movement of the shaft (12) relative to the housing (11) one of the race tracks (27) of the inner race ring (26) and the outer race ring (25) is formed cylindrical.
